Hi there,

I was trying to compare elements within two arrays to see if the two are the same. But when I ran the following code, the result disagrees with my expectation:

let a = [1, 2, 3];
let b = [1, 2, 3, 4];

function compare(a,b) {
for(i=0; (i < 3 || i < 4; i++) {
if(a[i] === b[i]) {
return “same arrays”;
}
return “different arrays”;
}
}

console.log(compare(a, b)); //same arrays

I am wondering why the comparison didn’t turn out “different arrays”
